C-V measurement is the powerful tool to gain further insight into the device physics of 2D materials. We have successfully measured quantum capacitance (C_Q) in monolayer MoS₂ FET. C_Q is originally derived from the finite DOS of a 2D electron gas and Fermi distribution. With increasing channel thickness, the electron distribution in the finite channel thickness should contribute to the total capacitance (C_total). Here, we discuss thickness dependence of quantum-mechanical effects in MoS₂ FET.
